[GiNaC-list] archiving custom functions

Archiving works fine, viewing the archives with viewgar -d gives me a complete output, without the -d switch viewgar complains about a non-existent function (logically!).

I tried now on another system with a newer compiler, and also get a segmentation fault, so it seems it's not a compiler bug. I'm using the newest CLN and GiNaC, self-compiled and also openSuSE packages, both don't work.
Looking through the source code, unarchiving a function should also work with custom functions, since they search for the function serial by name. My guess would be that the unarchiving code mistakes my function for a symbol which isn't passed, tries to create it and somehow segfaults there, but this is only an uninformed guess, I haven't dug that deep into the source code.
